I can’t get rid of 5XX errors from the google search console. I was able to figure out one potential issue causing this. It looked like a particular cloudflare IP was not whitelisted by the firewall on the server farm - so it would sporadically get blocked causing a fraction of users to get 5XX errors. We also fixed a timeout issue that was caused internally.
However, I am unable to get google search console to validate these fixes. They provide a list of about 800 URLs that it still thinks get 5XX errors. I try to click on them and I don’t see any problems. Is there any way to diagnose this issue to get to the bottom of it?
